$21027:12::32576:?$
The question presents a number logic puzzle. We need to find the relationship between the numbers in the first pair ($21027:12$) and apply the same logic to the second pair ($32576:?$) to find the missing number.
Number Logic Explanation
Observe the first pair: $21027$ and $12$. The logic connecting these two numbers is the sum of the digits of the first number:
- Digits of $21027$: $2, 1, 0, 2, 7$
- Sum of digits: $2 + 1 + 0 + 2 + 7 = 12$
The sum of the digits ($12$) matches the second number in the pair.
Applying the Logic
Now, apply the same logic (summing the digits) to the second pair's first number, $32576$:
- Digits of $32576$: $3, 2, 5, 7, 6$
- Sum of digits: $3 + 2 + 5 + 7 + 6 = 23$
Therefore, the missing number is $23$. This corresponds to Option B.
Important Questions from Number Based
- Below are given two sets of numbers. In each set of numbers, a certain mathematical operation on the first number results in the second number. Similarly, certain mathematical operations on the second number result in the third number and so on. Which of the given options follows the same set of operations as in question?
(NOTE – A two/three-digit number cannot be broken into individual digits for operations, e.g., if 37 is followed by 10, the operation cannot be 3+7 as a two-digit number cannot be broken into individual digits.)

5 – 20 – 60 – 120
8 – 32 – 96 – 192 Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.
(15, 7, 100)
(25, 8, 195)- Select the set in which the numbers are related in the same way as are the numbers of the following sets.
5-7-9
11-13-15
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding / subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed) Replace the question mark with an option that follows the same logic applied in the first pair.
